Patent CA-3066403-A1 (CA)
Title: Expanding anchor
Inventor: KAM ANDREW
IPC: A61F2/08
Filed: 2018-06-11
Abstract: An anchoring system for a knee ligament reconstruction that can secure a graft within a bone tunnel. The anchor system includes an anchor having a tubular body extending along a longitudinal axis from a proximal end to a distal end. A conical head is fixed to the distal end of the tubular body. A series of expandable segments are positioned along the tubular body and moveable along the body into a compacted, deployed position where the segments expand radially to engage the inside of a bone tunnel. A threaded drive member may move the segments to the deployed configuration once the anchor and graft are positioned in the bone tunnel. A drive tool may be used to advance the drive member and can include a moveable shaft that pushes a strike plate out of the rear of the handle to provide an indication whether the anchor has been fully deployed.

Patent CA-3069938-A1 (CA)
Title: Isolation of target nucleic acids
Inventor: GLOVER WILLIAM
IPC: C12Q1/683
Filed: 2018-06-13
Abstract: The invention provides methods of isolating a target nucleic acid in a sample. A primer is hybridized to the target. A polymerase and modified nucleotide resistant to nuclease degradation are used to extend the primer to create a modified polynucleotide. The sample is exposed to a nuclease, thereby isolating the modified polynucleotide. Optionally, the target nucleic acid may be further protected by binding a protein in a sequence specific manner to one end of the target nucleic acid to create a protected target nucleic acid resistant to nuclease degradation. Thus, after exposing the sample to a nuclease, the modified polynucleotide and protected target nucleic acid are isolated.

Abstract: La présente invention concerne une méthode de traitement du vitiligo chez un sujet dont l'état le nécessite, comprenant une étape d'administration audit sujet d'une quantité thérapeutiquement efficace d'un antagoniste de CXCR3B. Les inventeurs ont démontré que dans des échantillons de peau et de sang prélevés chez des sujets atteints de vitiligo, la population du système immunitaire inné est accrue (cellules NK et ILC1). Pour la première fois, les inventeurs ont montré que les mélanocytes expriment CXCR3 et, plus particulièrement, CXCR3B (expression d'ARN et de protéines). Ils ont montré que l'expression de CXCR3B sur les mélanocytes est responsable de la destruction des mélanocytes suite à une stimulation locale à l'aide de CXCL10. Les inventeurs ont démontré pour la première fois que l'ARNsi de CXCR3B ou l'antagoniste de CXCR3B empêche l'apoptose, induite par CXL10, des mélanocytes. Cette apoptose initiale des mélanocytes déclenche l'immunité secondaire adaptative contre les mélanocytes (15) qui détruit encore davantage les mélanocytes restants. En conséquence, les inventeurs ont découvert une nouvelle cible pour la prévention et le traitement du vitiligo.
